Acoustic Neuroma Conductive Hearing Loss: Understanding and Treatment
Acoustic Neuroma, also known as vestibular schwannoma, is a non-cancerous brain tumour that affects the nerve responsible for transmitting sound from the inner ear to the brain. This tumour can cause conductive hearing loss, which means the hearing sound is impaired because of problems in the middle or outer ear.
At Carlow Hearing, we understand the impact of hearing loss on an individual's quality of life, and we offer hearing aid treatment options for acoustic neuroma conductive hearing loss.
What is Acoustic Neuroma?
It is a non-cancerous tumour that develops on the nerve that connects the inner ear to the brain (vestibular nerve). It typically grows very slowly and may not cause symptoms for many years. However, as the tumour grows, it can pressure the nerve and cause hearing loss, tinnitus, and other symptoms.
What Causes Acoustic Neuroma?
The exact cause of this disease is unknown. However, there are a number of factors that may increase the risk of developing the condition, including:
Family history
Exposure to radiation
Certain genetic conditions, such as neurofibromatosis type 2
Symptoms of Vestibular Schwannoma
The symptoms can vary depending on the size and location of the tumour. Some common symptoms include:
Conductive hearing loss
Tinnitus (ringing in the ear)
Vertigo (dizziness)
Balance problems
Headaches
Facial weakness or numbness
Weakness or numbness in the arms or legs
Types of Hearing Loss Associated with Vestibular Schwannoma
Conductive Hearing Loss
It occurs when a problem with the outer or middle ear prevents sound from reaching the inner ear. Various factors, including fluid buildup in the middle ear, damage to the eardrum, or problems with the bones in the middle ear, can cause this type of hearing loss. In the case of acoustic neuroma, the tumour can put pressure on the middle ear and cause conductive hearing loss.
Sensorineural Hearing Loss
It occurs when there is damage to the inner ear (cochlea) or the nerve pathways that carry sound from the ear to the brain. This type of hearing loss is often permanent and can be caused by various factors, including age-related hearing loss, exposure to loud noises, and certain medical conditions. In the case of acoustic neuroma, the tumour can put pressure on the vestibular nerve and cause sensorineural hearing loss.
Diagnosing Acoustic Neuroma Conductive Hearing Loss
Diagnosing conductive hearing loss in individuals with vestibular schwannoma typically involves a combination of physical exams, imaging tests, and hearing tests. Some common diagnostic tests used to evaluate conductive hearing loss in individuals with an acoustic neuroma include:
Physical Exam
A physical exam evaluates the individual's overall health and identifies any signs of conductive hearing loss, such as fluid buildup in the middle ear.
Imaging Tests
Imaging tests, such as MRI or CT scans, are used to visualise the inner ear and identify abnormalities, including vestibular schwannoma.
Hearing Tests
Hearing tests, such as pure-tone audiometry or tympanometry, evaluate the individual's hearing ability and determine the extent and type of hearing loss.
Managing Acoustic Neuroma Conductive Hearing Loss
If you have been diagnosed with acoustic neuroma conductive hearing loss, you can take several steps to manage your hearing loss and improve your quality of life.
Monitoring and Regular Check-Ups
Monitoring the tumour's growth and regularly seeing your doctor to assess its impact on your hearing is important. Your doctor may recommend regular MRI scans to track the development of the tumour.
Hearing Aids
Hearing aids can be an effective solution for managing conductive hearing loss caused by acoustic neuroma. Hearing aids amplify sound and make it easier to hear, even in noisy environments. Various hearing aid styles and options are available, and your audiologist can help you find the right one for your needs.
Cochlear Implants
In severe cases, cochlear implants may be an option. A cochlear implant is a small, surgically implanted device into the inner ear. It bypasses the damaged part of the inner ear and directly stimulates the nerve responsible for hearing.
Surgery
In some cases, surgery may be necessary to remove the tumour and restore hearing. Several surgical techniques can remove vestibular schwannoma, including conventional open surgery, minimally invasive endoscopic surgery, and stereotactic radiosurgery. Your doctor will recommend the best surgical option for your case.
Speech and Language Therapy
If you are experiencing difficulty communicating, speech and language therapy may be helpful. A speech and language therapist can work with you to develop strategies for improving your communication skills and help you regain confidence in your ability to communicate effectively.
